(1) As a rule of thumb, start with a shade that is too dark, then go to a lighter shade which gives sufficient Data from ANSI Z49.1-2005

view of the weld zone without going below the minimum. In oxyfuel gas welding or cutting where the torch produces a high yellow light, it is desirable to use a filter lens that absorbs the yellow or sodium line the visible light of the (spectrum) operation
